CHANGES:

• Cohttp_async.resolve_local_file, Cohttp_lwt.resolve_local_file and Cohttp_lwt_unix.resolve_file are now the same code under the hood (Cohttp.Path.resolve_local_file). The old names have been preserved for compatibility, but will be marked as deprecated in the next release. This changes the behavior of Cohttp_lwt_unix.resolve_file: it now percent-decodes the paths and blocks escaping from the docroot correctly. This also fixes and tests the corner cases in these methods when the docroot is empty. (@ewanmellor #755)
